APPARATUS FOR LIGHTI NG GAS BY ELECTRICITY.

SPECIFICATION forming part of Letters'Patent No. 284,784, dated September 11, 1883. Application filed June 1,1883. (N0 model.)

To all whom it may concern Be it known that we, HENRY J. WARREN and HENRY F. PACKARD, residing at the city of Brockton, county of Plymouth, and Common wealth of Massachusetts, have invented a new and useful Improvement in Apparatus for Lighting Gas by Electricity, of whichthe following, taken in connection with the accompanying drawings, is a full, clear, and accurate description.

The object of our invention is to provide a gas-cock for use in burners lighted by electricity of such mechanism that all leakage by neglect to close the gasway is avoided, and also to provide means in said burners to prevent the grounding of the electrical current used to light the same.

In the drawings, Figure 1 represents a front view of our improvement. Fig. 2shows a side elevation of the same. p

A is a stop-cock at the base of the burner B.

Upon the stop-cock A is pivoted a lever, 0, provided with the arms D and E. In front of said lever O, and firmly secured to stop-cock A, is placed a clutch-wheel, F, provided with,

preferably, eight teeth. These teeth are arranged alternately, one tooth being square and the next tooth being beveled on one side.

On the arm D of lever O is placed a pawl, G, having out therein a recess, into which the square teeth of the clutch-wheel F will fit. The free end of said pawl G is beveled, and said pawl is held against the clutch-wheel F by the spring H, or other suitable device.

Upon the arm E of the lever C is secured the igniting-wire I, projecting above the arm E, and terminating in a wiping-point bent at Around the stem of the stop-cock A, be tween the lever O and the base of the burner, is coiled a spiral spring, J. One end of said spring J rests against a pin, K, on the back of the arm E,-and the other end of said spring against a post, L, upon the base of the burner. immediately below the lever 0, said post L holding a pin, 1.

Upon the lower part of the lever O are the two projections or stops 0 0.

Above the stop-cock A there is attached to the base of the burner an insulating-block, M,

to which is pivoted a metallic bar, 0, which we call the igniting-bar, of such length as to reach above the tip of the burner, and terminating in a narrow portion or a wire. The lower-part of this ignitingbar O is formed with two projections or arms, P and R, placed at right angles to each other.

At one side of the insulating-block is placed a metallic stud or stop, S, in such a position that when the igniting-bar is in a vertical position the arm 1? will rest in contact with said stud or stop S. This stud'or stop-S is connected with one wire leading to the battery by the binding or set screw T, the other wire being connected with the burner at any desired point. A pin, W, may be placed at the other side of the insulating-block M to pre vent the igniting-bar 0 from moving too far in that direction The arm D of the lever C can be provided with a cord, chain, or other suitable device for moving the same. The igniting-bar 0 may be provided with a retractile spring to hold and bring it back from the contact with the stop S. The motion of the lever O is limited by the stops 0 c acting on the pin Z.

The mode of operation is as follows: When it is desired to turn on the gas, the arm D is pulled downward, and the pawl G, engaging with one of the square teeth of the clutchwheel F, carries it downward, thus opening the gasway in the burner B. At the same time the wiping-point of the igniting-wire I, being pressed against the narrow portion or wire of igniting-bar O, forces the said bar into an upright position, carrying the arm P into contact with the stop S, and thereby establishing an electric circuit. A continued downward motion of the arm D forces the wipingpoint past the igniting-bar 0, thus making a spark at the tip of the burner, and thus lighting the gas. As the wiping-point passes the igniting-bar the free beveled end of the pawl G is pressed against the pin Z, and the pawl is forced free from the tooth of the clutchwheel F, and the lever G, being left free, is carried to its normal position by the force of the spring J, the pawl G passing over the edge of the square tooth, and engaging, by means of the spring H, with the beveled tooth of the clutch-wheel F, which is next. At the ioo same time the pin K, coming in contact with the arm R of the igniting-bar O, forces said bar backward and out of connection with the stop S, thus breaking the electric connection.

The igniting-bar is also carried back out of connection with said stop by the backward movement of the wiping-point as the lever G resumes its normal position. ment of the arm D (when, as described, the pawl G is engaged with the square tooth of the clutch-wheel F) is not sufiiciently far to sired to regulate the supply of gas, the arm D is again moved dow11ward,the pawl G carrying with it the beveled tooth with which it is engaged. \Vhen this is carried down as far as is desired to partially cut off the gasway, the lever may be released, and the pawl disengagesitself from the tooth by means of the bevel thereon and passes over the outer edge. If it is then desired to turn off the gas en-- tirely, the arm D is again brought downward, the pawl engages with the same beveled tooth and forces it still farther down, until the beveled end of the pawl is forced against the pin Z, as before, and freed from the tooth and the gasway completely shut off. The pawl G, in its backward movement, the lever being freed, passes over the edge of the beveled tooth and engages with the next square tooth, at the same time the operation with the wipingpoint and igniting-bar is repeated, so that it.

will be seen that an electric spark is generated each time the gas is turned completely on or oif.

The above description, with the drawings, shows one way in which the igniting-bar may be insulated, except when it is desired to make and break the circuit for the purpose of lighting the gas. I l

Having thus described our invention, what we claim, and desire to secure by Letters Patent, is-

1. A stop-cock for gas-burners, having pivoted thereon a lever carrying a spring-pawl provided with a recess and beveled end, a clutch-wheel attached to said stop-cock, having alternately square teeth and teeth beveled on one side, and a disengaging-pin and retractile spring attached to said lever.

2. In apparatus for lighting gas by electricity, an insulating-block attached to the gas-burner, having thereon an igniting-bar with a projecting arm, a metallic stud in an If the movenected with one wire of the circuit, a lever carrying awiping-point, acting to force the igniting-bar into contact with, and a pin acting to force said igniting-bar out of contact with said metallic stud, and a retractile spring attached to said lever, being electrically con nected with the other wire of the circuit.

4. In apparatus for lighting gas by electricity, an insulating-block attached to the gasburner, having thereon an igniting-bar with projecting arms, a metallic stud in an insulatingblock attached to the gas-burner connected with one wire of the circuit, a lever carrying a wiping-point, acting to force the igniting-bar into contact with said metallic stud, a pin or projection on said lever, acting to force the igniting-bar out of contact with said metallic stud, and a retractile spring attached to said lever, said lever being electrically connected with theother wire of the circuit.

5. In apparatus for lighting by electricity, a stop-cockprovided with a two-arm lever electrically connected with one wire of the circuit, and a clutch-wheel having alternately square teeth and teeth beveled on one side, a disengaging-pin anda retractile spring, one arm of said lever being furnished with a spring-pawl provided with a square recess, and the other arm of said lever being furnished with a wiping-point, in combination with insulating-blocks attached to the gas burner, and provided with an igniting-bar and a metallic stud connected with the other wire of the circuit, the parts of said apparatus being so arranged in relation to each other that the motion of the lever forces the ignite ing-ba-r into and out of contact with the metallic stud on its insulating-block and makes and breaks the circuit.
